170 THE FOREST TREE CULTURIST. 
are native of different parts of the Old World; many of 
them are perfectly hardy in our Northern States. Seeds 
of several of the best and most common kinds are annu- 
ally imported by the seedsmen. The Pinus Cembra (Swiss 
Stone Pine), Pinus Corsica (Corsican Pine), Pinus Aus- 
triaca (Austrian Pine), and Pinus Sylvestris (Scotch Pine) 
are quite common, and to be found in all large nurseries. 
These and several other species are well worthy of being 
extensively cultivated. 
There are also many species that have been discovered 
on the Pacific coast and among the Rocky Mountains, but 
as yet they are rather scarce, and their true character as 
to hardiness is not fully known. 
SEQUOIA GIGANTEA. (Giant Sequoia.) 
This is the largest-growing evergreen tree known on 
this continent, and perhaps in the world, there being speci- 
mens now growing in California which are nearly if not 
quite four hundred feet high, with stems twenty to thirty 
feet in diameter. The leaves resemble the Arborvites, 
the cones are oval and about two inches long, seales thick, 
pointless; seeds small, winged on all sides; wood valu- 
able, somewhat similar to red cedar; tree of very rapid 
growth, but unfortunately not sufficiently hardy for gen- 
eral cultivation at the North, although in protected situa- 
tions it grows as far north as Central New York; not 
fully tested. 
Tnvsa occipenTaLis. (Arborvite.) 
In many portions of the country this is called Cedar;
